摘要

致密油开发多采用水平井多段多簇压裂的开采方式,而裂缝形状及延伸难以精确控制,压裂液污染严重,危害周边水体。针对上述问题,为了更加安全、高效动用致密油藏,提出了水平分支井聚簇孔井型开采方式,并通过模拟软件建立基于油水两相渗流分布机理的泄油模型。通过产能预测,选择分支夹角和位置布置最优的鱼骨形水平分支井,将此井型应用于水平分支井聚簇孔井型并研究其产注性能。研究表明:聚簇孔井型泄油面积更广、见水更快。聚簇孔井型具有较好的产注性能,施工周期更短、更加安全高效。相同条件下衰竭开采10 a后,聚簇孔井型相比鱼骨形水平分支井增产约11.12%;LD-1平台长71井组采用聚簇孔井型模拟开采4 a,平均日产油增加13.21%;邻井注采模拟条件下开采20 a,采用聚簇孔井型作为注入井,相较于鱼骨形水平分支井,单井累计产油量提升约23.7%。该研究可为聚簇孔井型的结构优化和致密储层的高效开采提供技术参考。

Abstract

The multi-stage and multi-cluster fracturing of horizontal wells is mostly used for the development of the tight oil, the fracture shape and extension are difficult to be precisely controlled, and the fracturing fluid contamination seriously jeopardizes the surrounding water bodies. To address the above problems and to utilize tight oil reservoirs more safely and efficiently, the clustered borehole type horizontal multilateral well pattern was proposed for oil production, and an oil drainage model based on the oil-water phase seepage distribution mechanism was established by simulation software. Through the capacity prediction, the fishbone-shaped horizontal multilateral well with optimal branching angle and location arrangement was selected, and this well pattern was applied to the clustered borehole type horizontal multilateral well and its production and injection performance was studied. The study shows that the clustered borehole well pattern has wider oil drainage area and faster water breakthrough. The clustered borehole well pattern has excellent production and injection performance, shorter construction period, higher safety and efficiency. After 10 a of depletion production under the same conditions, the clustered borehole well pattern increases production by about 11.12% compared with the fishbone-shaped horizontal multilateral well; the average daily oil production of the LD-1 platform Chang 71 well group increases by 13.21% after 4 a of simulated production using the clustered borehole well pattern; neighboring wells were extracted under simulated injection and extraction conditions for 20 a, the clustered borehole well pattern is used as the injection well, and the cumulative oil production of a single well increases by about 23.7% compared with that of the fishbone-shaped horizontal multilateral well. The study can provide technical references for the structural optimization of the clustered borehole well pattern and the efficient exploitation of tight reservoirs.

Key words： horizontal multilateral well; clustered borehole; production and injection performance study; seepage analysis; tight reservoirs
